Hi Dilip,
As you and Gabriel mentioned, the .msi allows you to install the entire UiPath suite: Studio, Robot(with all the rights of a Windows service), Orchestrator, while the .exe allows you to install Studio and Robot in user-mode(it has has same rights as the user under which it has been installed).
@whyyouandi If you choose Start Free you will get the CE regardless the installer because the Studio version(Community Edition or Enterprise) is given by the license.
More details in the Studio user guide:
